`Speeifl-cz1tion forming part of Letters Patent No. 82,043,` dated Septemberl 8, i868,

Conestoga. township, in the county of Lancaster and State of Pennsylvania, have made lcertain Improvements on' a Potato-Flow Conl vertible into a Cultivator; and I hereby declare'thatthe following is a full and exact dc` scription of the construction and operation of the'-same, referenee being had to the accompanying drawings, making a part of this speci- Iioation, in which-L 'Figure lis a, perspective viewIr of my po-A tato-plow; Fig, 2, the shifting center piece'` aiiixedto the centralbeam, A,betweeir'whiehn ndpole: shows theY position et; the three ishovels, peculiarly adapted to "plowing loutpotatoes; Fig. 'f 4,the twoA outer shovels andtheirbeams` reversed, the peculiar shape especially/' adapted for dressing corn, (the centralshovel and beam removed for that purpose) .and the pole, Fig'. 2, applied instead.

f- Theinature of my invention consists in the manner of adjusting my side beams, and in the vpeculiar construction of my shovels forme-...-

movingthesoil from the sides of a row of potatoes, and then turning up the row, so as to 'throw' thepotatoes to the surface, by reversing said. shovel on a separate rcenter beamthat is, the righthand shovel and beam of the one`coines onthe left-hand side of the other, used in one case for throwing the'V `soil fromthe row and in the otherto the row.

To enable any one skilled in the art to make and usefmy inventiomabrief explanation will suioe, y

`general construction is common tonumerous cl'llti'vators now in use,diiering, however, 'inthe 'construction of'v .the `shovels and arrangement 4of the shifting device. I For apotato-plow (Fig. 1 shows the arrangement)` I. employ square-headed 'screw-bolts b,

of a vuniform size, so that, one wrench, W,

(held in a :loop on the hand1es,)'willfit them all. IThe central beam, A, in the' form of hook behind, has the plow-shovel 1, adapted Vfor getting under and turning up the potatoes,- .while the side beams, B C, are provided' with shovels 3 2, with their inner edges nearlypar- `allel to each other, the sides rounded 'up and turned oif into side wing-like prolongations." These remove the soil by cuttingfdown the 6llgrvedsidesof the hilledrow and throwing f e soil outward to give the central shovel, 1, a clean sweep lfor turning out the contents of the said row. hese wings or side beams, B C, are madeadjustable by means of'a segmentbar, G affixed to the ceii'tembeam,and slid( 7 ing throghslots in the' side beams, and are providedwith dished holes to receive the end of a headed screw, b, which has its bearing in a female screw cut into the raised portion over the said slot, as shown, which holdstheu'af: justed beams in place, according to the-width of the hill or row. The collar-braces D D'are `the side beams are held, and move upon the headed bolts b. This central beam has two 'adjustable ovate segments, E,with a slot-andbolt attachment for the bearingfrof a pulleywheel, F, and said beam is also prolonged into combination forms an admirable implement. for unearthing potatoes or thelike,

into a "pole, a, A, Fig. 2, and has a segmentbar, G, and the collar-plates D vD attached, and 4is also provided withholes k h,fo r the bolts to fasten the handlesto the same. lThus it is adapted to receive the side beams, B C, with their respective shovels,3 2,and the handles H.

position, so that the' straight or winged sides of said shovels are now brought td'the outside, or farthest from the row, and, properly adjusted, ;will be' found `ttcd in a' peculiar Inanner to throw, the soil inward, and to the rnots mirably .adapted for dressing corn.

'sition" the"soil is thrown outward, and 3when v reversedto thro-w'thesameinward. Usefulas I know my arrangement tobe, I

a hook, I, for the attachment of ahorse.VV This' The' separate centerbeam referred to i'snot provided wtha shovel, but may be prolonged The side beams are, however, reversed in their l of the standing corn, from each side, as illustrated by Fig. 4, and forms an implement'ad- I amaware that hinged and adjustableside am-fawareof the numerous inventions alreadyA patented, and must consequently confine my- G, 'and aq'iustable bearings E, in combination self simply to the arrangement of the Whole with 0r without the' separate center piece, A, combination, asl differing substantially from Fig. 2, :L11 made in the nmnner'an'd for the pm'- others, e'0nsidered as a Whole; therefore pose speci-lied.

What I claim asgny invention, and desire to secure by Letters Patent, is-. L
